An optical interferometer includes a branching-combining unit, a first optical system, a second optical system, and a drive unit. The branching-combining unit includes a branching surface, an incident surface, a first output surface, a combining surface, and a second output surface on an interface of a transparent member, the branching surface partially reflects incident light and outputs as first branched light, and transmits the rest of the incident light into the interior as second branched light, the combining surface partially combines the first branched light and the second branched light to be output to the outside as first combined light, and combines the rest of the first branched light and the second branched light to be propagated into the interior as second combined light, and the second output surface partially outputs the second combined light to the outside.

Optical interferometer

An optical module includes an actuator that includes a movable part to be moved along a predetermined direction; a first interference optical system that includes a first movable mirror, a first stationary mirror, and a first beam splitter; and a second interference optical system that includes a second movable mirror, a second stationary mirror, and a second beam splitter. The first interference optical system is adapted so that first light reciprocates m times (m is a natural number) between the first beam splitter and the first movable mirror along the predetermined direction. The second interference optical system is adapted so that second light reciprocates n times (n is a natural number greater than m) between the second beam splitter and the second movable mirror along the predetermined direction.
